 note = {Tuning bars or free-free bars are in use for the independent synchronization of Facsimile and Telephoto-transmission instead of tuning folks.
Tuning bars are excellent in the simplicity of the form, and oscillators with these bars have good stability of the frequency. In this paper the author has given some notes regarding tuning bars, that is to say, non-linear vibration， zero temperature coefficient materials, temperature coefficient of bimetal tuning bars, radiation impedance, vibration losses, and new method of excitation of non magnetic materials., 音片とは周知の様に，自由－自由棒であって，音叉或は音環に代り，模写電信叉は写真電送の独立同期用電源として利用せられて居るもので，製作の容易さと精度（周波数温度係数の少いことと電源電圧変動に対する安全度の高いこと）の優秀な特徴がある。著者も此の音片の特性向上のために二三研究する機会を得たので，茲に取りまとめて報告し，諸彦のご参考に資したいと考えて居る。, Article, 富山大学工学部紀要, 4(1/2), Page 26-36},
